When and where are these held and where do you enter?

durrrrrrrrrrrrrrrrrrrrrrrrr

What type of tourney are you looking for? Walleye, bass, crappie, ect...?

Little more info on what you want would be helpful...

I thought I read something about tournaments on pyma. But I may have been mistaken??

This is what perhaps you were trying to get too. Pymatuning Lake association holds tournaments every year on the lake.  Early spring/summer there are crappie and walleye tournaments.

Walleye LINK ->

And also there is a kids fishing derby LINK ->

For bass tournaments your on your own....
